The accelerator of the new car is broken. Can I buy a new car?

If the valve is broken, you don't need to change the tire, for the same reason.

Throttle failure is not uncommon, and any model may appear.

The position of the throttle valve in the engine is equivalent to the valve in the tire. Just change it. There is no need to change to a new car.

Unless you find that the new car has other serious problems that you can't stand.
